Reddit reviews Enzotech Graphics Card Passive Heat Sink, 14 x 14x 14 mm, Copper, 8-Pack

[Here] (https://www.amazon.com/gp/aw/d/B002BWXW6E/ref=mp_s_a_1_2?ie=UTF8&qid=1484524030&sr=8-2&pi=AC_SX236_SY340_FMwebp_QL65&keywords=vram+heatsink&dpPl=1&dpID=51Gxy4PJibL&ref=plSrch) is one. Amazon "VRAM heatsink" and you can find a few other kinds.

I got some of these for a couple of Rpi3's.

Now I have heat-sinks for 6 more Pi projects.

Something like this would work well. I'm with Zsilfen on the vram having some kind of cooling.

I didn't see that one, and wound up with an interesting looking fan case. It uses a 5v, 10mm by 80 mm fan which is very quiet.

Then I stuck a forged copper heatsink on the Pi and wedged a business card in the case to duct the airflow to come up by the USB ports, over the CPU and out by the micro SD slot.

You know I was wondering the same thing when I watched the video. At the time I couldnt find any answers and gave up for a while. I am planning on eventually opening my sc2 hybrid up trying different things. Hopefully there will be some solutions by then.

Was also going to try putting these [copper heatsink pins] (https://www.amazon.com/gp/product/B002BWXW6E/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1) on the cold plate extensions that are covering the memory modules. I think theres enough room for them to squeeze inside, if not I was thinking the backplate over the vrms. More curious than anything to see if I can get a noticeable temp drop.

Currently looking at:

• Enzotech heatsinks.
  
• This larger single sink.

I would pick up an new PSU like this CX600 or this EVGA 650, which will work for this and future builds, and a go for it. The only other thing I would recommend is adding heatsinks to the VRMs beside your processor circled in first pic. That will help keep everything cool and stable while overclocking. These large memory sinks or these smaller VRM sinks just stick on and work well.

If you've got the space clearance, you can always add some ramsinks to the chips. Chances are you don't need it, but it can't really hurt.

Unless you find a R5 1600(X) for a really good deal (e.g. R5 1500X for $100, R5 1600 for $138, R7 1700 for $196, etc), you'll be fine just waiting for the R5 2600. Technically you would also be fine with the R3 1200 and could choose to wait for the Ryzen 3000 series CPUs that are coming out next year.

I'm not sure about the motherboard though. Maybe you'll want to add some little heatsinks to the mosfets (maybe put a case fan on the vrms as well) to reduce the temps or just get a new motherboard altogether; the safer option that would also give you peace of mind would probably be the latter.

    Heatsinks you can put on the vrms; they come with their own thermal tape:
    
    $5.88 Aluminum Heatsinks
    
    $20 Copper Heatsinks

    Or $8 Copper Shims that can be used as copper heatsinks.
    
    Use with thermal tape or very viscous thermal paste like Ceramique 2.
    

The thermal adhesive is incredibly strong. I'd recommend mixing it 50/50 with thermal paste if you ever want to remove the heatsinks.

Also, you can buy proper heatsinks with thermal pads. Something like this: http://www.amazon.com/dp/B002BWXW6E/

The fans you have picked out don't suck, but they're more expensive than they should be and louder than better fans. The do look pretty, but that's what you're paying for.

I bought two of these; http://www.scan.co.uk/products/140mm-phanteks-ph-f140hp-white-frame-white-blade-pwm-premier-cooler-fan

I got them for a Hyper 212 air cooler, but they should work great for you. The only catch is that they're 140mm fans (with 120mm mounting holes) so they're bigger than a 120mm fan, but they'll fit on a radiator or heatsink with 120mm mounts.

They're absolutely silent, move 90cfm at 1300 RPM, they're cheaper than the fans you had picked out, and they're high pressure (HP) fans specifically built for radiators or heatsinks. They come in four different colors too.

These are the little heatsinks with stick-on thermal pads that I was talking about; http://www.amazon.co.uk/Enzotech-Graphic-Memory-Heatsinks-BMR-C1/dp/B002BWXW6E

Don't forget that the VRAM modules need to be cooled too, I don't know if the G10 bracket takes care of that or what, but just blowing air on them isn't enough. If they don't have a heatsink on them they need one. That could also be causing stability issues.

Something on that card is getting too hot and giving you problems, there's no reason it wouldn't be stable at 150mv+ on water cooling when it is on air.
